Page 5: Intended Use
1. INTENDED USE Platform scales are designed for fast and precise measurements of weighed loads masses and direct commercial settlements. Tarring in full weighing range enables to determine net mass of weighed loads. Additional display is additional equipment of scale. It is to control mass of weighed load by another person. -
Page 6: Power Supply Of Weighing Indicators In Plastic Casings
The device connected to mains inteligently monitors the battery state and charges it if possible. After sudden lack of power supply from the mains the device automatically switches to accumulator without breaking operation. In case of an elongated storage period in low temperatures, it is not allowed the full discharge of the accompanied batteries. -

Notice: Filtering level influences the time of stabilization. The higher the filtering level is the longer stabilization time is needed. Return to weighing: See - 10.2.2. 12.2. Median filter This filter eliminates short changes (impulses) of measure signal (e.g. shocks). Procedure: •... -
Page 23: Autozero Function
12.3. Autozero function The autozero function has been implemented in order to assure precise indications. This function controls and corrects „0” indication. While the function is active it compares the results continuously with constant frequency. If two sequentional results differ less than the declared value of autozero range, so the scale will be automatically zeroed and the pictograms will be displayed. -
